Python operator ** (two multiplication signs are the multiplication party), and python multiplication party

A multiplication Number *. If the operand is two digits, the two digits are multiplied. For example, 2*4, the result is 8.
** Two multiplication signs are the multiplication parties. For example, 3 ** 4, the result is the 4 power of 3, and the result is 81.

* If the string, list, And tuples are multiplied by an integer N, an object of the same type with all its elements repeated N times is returned. For example, "str" * 3, a string "strstrstr" is returned"

If the * Before the parameter in the function definition indicates that multiple parameters are put into the tuples during the call, ** indicates that the keyword parameter used to call the function is put into a dictionary.
Args = (1, 2, 3)
Func = (* args)
It is equivalent to function call func (, 3)

Print (3 ** 4) # The result is 81str = input ('input a string') print ('use str * 3 to output three times str: ', str * 3) # * If the string, list, And tuples are multiplied by an integer N, an object of the same type with all its elements repeated N times is returned.
